Giant ferromagnetism and exchange bias in tensile strained and Cr modified CaRuO3 thin films
We present an unified approach of epitaxial strain and chemical substitution to induce ferromagnetic order in otherwise non-magnetic CaRuO3. The tensile and compressive strained CaRu1−xCrxO3 (0

The tensile and compressive strained CaRu1−xCrxO3 (0 < x ≤ 0.2) (CRCO) films deposited on SrTiO3 (100) and LaAlO3 (100) substrates, respectively, exhibit a magnetic moment larger than their bulk compositions. The compressive strained x = 0.15 film displays unusually large magnetic moment ∼1.4 μB/f.u. which is about one order of magnitude larger than that of its bulk counterpart.
